•     concept art
•     texture and matte painters
•     illustrations and comics

Krita 3.1.4 Changelog:

•     Fix a crash when trying to play an animation when OpenGL is disabled in Krita
•     Fix rendering animation frames if the directory you’re trying to render to doesn’t exist
•     Don’t open the tablet/screen resolution conflict dialog multiple times
•     Don’t scale down previews that are too small in the transform tool: this fixes a rare crash with the transform tool
•     Don’t crash when trying to close the last view on the last document while the document is modified.
•     Fix a crash when cycling quickly through layers that have a color tag
•     Fix loading some Gimp 2.9 files: note that Gimp 2.9’s file format is not officially supported in Krita
•     Fully remove the macro recorder plugin: in 3.1.4, only the menu entries had stayed around.
•     Make it impossible to hide the template selector in the new image dialog; hiding the template selector would also hide the cancel button in the dialog.
